What is the initial phase of the Eukarya cell cycle?

1. Interphase

2. Mitosis

3. Prophase

4. Cytokinesis

The correct answer is: Interphase

The initial phase of the Eukarya cell cycle is Interphase. Mitosis, Prophase, and Cytokinesis are all different phases that occur during the Eukarya cell cycle but they do not mark the beginning of the cycle. Mitosis is the phase where the cell's nucleus divides, Prophase is the first stage of Mitosis where the chromatin condenses into chromosomes, and Cytokinesis is the final stage of the cell cycle where the cell fully separates into two daughter cells. Interphase is the first and longest phase of the cell cycle where the cell grows and prepares for division. Therefore, Interphase is the correct answer as it marks the beginning of the Eukarya cell cycle.
